Relation between input current and calculated concentration

Figure 50 shows the output current depending on the process value, the set low value

and the set high value with an output range of 0–20 mA.

The output current (OC) is a function of the process value (PV).

The output current is determined by formula (1):

(1)

where:

OC=Output current

PV=Process value

LV=L ow va lue

HV=High value
